B OC 1 A small disc A placed on a frictionless tabletop is connected to a small protrusion B on the tabletop with the help of an almost inextensible elastic cord of relaxed length 1 There is a trap C in the table at distance n 0 5 times of 1 from the protrusion Initially the disc the protrusion and the trap are in a line and the cord is straight and relaxed as shown in the top view of the setup At what angle with the line AC must the disc be projected along the tabletop so that it enters the trap Diameter of the protrusion is negligible as compared to the length of the thread
